I am having a problem with texturing. The map looks distorted. I tried UVW unwrapping. The checkered map looks fine. But the actual texture is distorted. How can I fix this? I have never used UVW unwrapping before. I might be doing something wrong.
Thank you!

Did you check if a) your material has triplanar nodes, or b) your textures are set on different mapping channel?

I didn’t know about triplanar nodes before. I used here and it definitely gives a better result. Thank you so much!

Proper UV unwrap is in fact superior on models like yours and therefore it should be prioritized over triplanar, but if latter is giving you better results, then why not, you can use it as well :]

Yes. It worked better for a particular map. But does not give overall better output. I should try something else with unwrapping. I can't figure out why it looks fine as checker map, but not with the actual.

Can you show how unwrapped UVs looks?

Sorry I didn’t understand. Please excuse my inexperience.

Add unwrap UVW modifier on the model, open UV editor window and take a screenshot like this.

Sorry I was offline for a few days because of a family emergency. The distorted map problem was kind of solved. But there is still a problem. You can see in the attachment that the map is inconsistent. The unaltered version of the model had seams in this pattern. Then I applied a uvw mapping clear modifier and converted it to editable poly to create my own seam. But in the end, the texture seems to follow the initial seams. I feel like I am missing some of the steps.

Make sure you are using the same map channel in your UVW modifier and the bitmap. (see screenshot)
For quick texturing you can also use the Corona Triplanar Map and forget about unwrapping - https://docs.chaos.com/display/CRMAX/Corona+Triplanar+Map

It seems that is not a mapping issue, but a shading problem. It's hard to tell what's exactly going on, it could be shadow terminator, or black highlights issue, or something else. Try to subdivide the mesh and see if artifacts get less visible. Also try to isolate the object and render it without anything else in the scene, see if that helps to identify the issue.
